DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Best Mode for Carrying Out the Invention

The benefits and characteristics of the present invention and methods of implementing them can be clarified by referencing to preferred embodiments of the invention to be described along with the attached drawings.

The following describes a preferred embodiment of the present invention by referencing the attached drawings.

FIG. 1 is a section view of the internal structure of the container assembly of the present invention and FIG. 2 is an exploded perspective view of Part B of FIG. 1.

As illustrated here, the present invention is comprised of the container body 100, the transfer tube 200 featured in it, and the quality maintenance unit 300.

The container body 100 features the internal space 101 that accommodates contents 500 which are fluids and the nozzle assembly 110 at the top that ejects the contents 500.

Depending on the type of contents in the internal space 101, the container body 100 is made of synthetic resin, or of metal such as aluminum or aluminum alloy, allowing for a variety of applications and modifications.

In other words, if it accommodates colloid fluids with certain viscosity such as detergent like shampoo or body washer or kitchen detergent, it can be made of synthetic resin; if it accommodates chemicals such as hairspray, paint, adhesive, insect repellent, or spray pain killer, since the container body 100 acts as a pressure housing, it should be made of metal such as the types described above.

On the container body 100 a protruding part can be added to help users grab it and use it more conveniently, or other applications or modifications can be made to the design, such as a concave surface in the middle of the container body to apply pressure to eject the contents 500 properly.

In addition, the nozzle assembly 110 is designed to let flow or dispense the contents 500 in the internal space 101 by means of push operation, but since it has a similar structure to existing ones, its detailed structure and mechanism will not be described here.

The transfer tube 200 is connected to the nozzle assembly 110 and into the internal space, and forms a fluid path on which the contents 500 are transferred through the nozzle assembly 110. Not only does it act as a transfer path allowing the contents 500 to be absorbed and ejected through the nozzle assembly 110, but it also serves as a support member that provides space and area where the quality maintenance unit 300 as described below is mounted.

The quality maintenance unit 300 is coupled to more than one transfer tube 200 and moves along with it, while mixing the contents 500 in the internal space 101 and maintaining the state and quality of the contents 500 to be ejected through the nozzle assembly 110.

Here the quality maintenance unit 300 should provide protection against deterioration or deformation in the physical appearance of the contents 500 in the internal space 101 caused by a variety of structures and embodiments, such as rotation, reciprocation, or elastic deformation within certain limits as shown in FIGS. 1 and 2, which will be described in detail later.

While the embodiment of the present invention as described above can apply, the following embodiments can be also made possible:

To begin with, if the contents 500 accommodated by the container body 100 are hair spray, paint or adhesive, it can congeal or harden if not used for a long time and may not be ejected through the nozzle assembly 110. Therefore, there should be at least one ball 400 for mixing purposes that can move freely in the internal space 101 of the container body 100.

Here, such a ball 400 should be of the size and weight that does not cause the ball to collide with the quality maintenance unit 300 or affect the operation of the quality maintenance unit 300.

Therefore, the user can prevent the deterioration of the contents 500 and maintain their quality by grabbing the container body 100 and shaking it multiple times for a certain time period with a certain frequency.

Meanwhile, the quality maintenance unit 300 is featured in the transfer tube 200 and designed to maintain the quality of the contents 500 of the internal space 101, which also includes movers 310 and multiple blades 320 as shown in FIGS. 1 and 2.

The movers 310 are coupled to the outside surface of the transfer tube and rotate clockwise and counterclockwise, while multiple blades 320 are coupled to the outside surface of each mover 310 and rotate along with the mover 310.

Here, the multiple blades 320 connected to the mover 310 rotate clockwise and counterclockwise, practically mixing the contents 500, and they are made flat and widen towards the outer edges.

These multiple blades 320 can be given an inclination relative to the movers 310 to maximize the effects of mixing the contents 500 by the rotating force.

Also, though it has not been specifically illustrated, a system like a spring can be mounted between the mover 310 and the transfer tube 200 allowing the mover 310 to rotate clock-/counterclockwise rotating motion around the axis of the transfer tube 200 while being connected to push operation up/down reciprocating motion of the nozzle assembly 110 to rotate the multiple blades 320.

If the movers 310 are not used for a long time, since the load of a mover 310 may cause it to drop to the bottom of the container body 100, each mover should be kept at a certain height or protrusions 315 can be added so that the mover 310 can rotate clock- or counterclockwise.

Those protrusions 315 created on the outside surface of the transfer tube 200 prevent the movers 310 from moving further down than a certain location. Multiple protrusions 315 are arranged on the transfer tube 200 lengthwise while multiple movers 310 are arranged on the transfer tube 200 lengthwise.

The movers 310 are made to rotate in different directions depending on circumstances, causing a swirl in the internal space 101 and mixing the contents 500 evenly.

In another embodiment, multiple beads 321 can be placed in the direction the blades 320 are formed to increase the efficiency of mixing by adding loads on the blades 320.

These beads 321 rotate along with each blade 320 or increase mixing efficiency by producing several swirls near the surface of the blade 320, depending on the rotation of the blades 320.

Those blades 320 can be arranged in helical or radial shape with different heights along the outside surface of the movers 310 as shown in FIG. 2, increasing the efficiency of mixing and helping maintain the quality of the contents 500.

These multiple blades 320 can be made as flat plates but also as frames with the edges illustrated as members of a steel wire or narrow, long rod. Multiple wires are then arranged width- and lengthwise, and multiple beads 321 can be coupled though so that the beads can freely rotate on each wire.

In the embodiment above, the user can lift up the container body 100 and shake it to allow the aforementioned ball 400 to maintain the quality of the contents 500, and make the quality maintenance unit 300 including the movers 310 and blades 320 mix the contents 500, contributing to quality maintenance.

The present invention allows for a variety of applications and modifications, such as that the user can operate the quality maintenance unit 300 by grabbing and shaking the container body 100, or turn it clockwise or counterclockwise using the mechanism of the aforementioned spring when operating the nozzle body 110.

In another embodiment of the present invention, as shown in FIG. 3, the efficiency of mixing the contents 500 can be increased using the elastic deformation of a coil spring 330.

In other words, in the quality maintenance unit 300, the movers 310 are coupled to coil springs 330 and multiple blades 320 are then coupled to each mover 310.

The coil spring 330 is coupled on the outside surface of the transfer tube 200, producing elastic deformation lengthwise along the transfer tube 200 caused by vibration arising from the user's grabbing and shaking of the container body 100.

When coupled to the coil spring 330, the mover interacts with the elastic deformation of the coil spring 330 along the length of the transfer tube 200, allowing for reciprocating motion to a certain extent.

The multiple blades 320 are coupled on the outside surface of this mover 310 and move up and down along with the mover 310, helping to mix the contents 500 and preventing deterioration.

Here, the internal surface of the mover 310 should be placed with a certain clearance from the outside surface of the transfer tube 200 when coupled to the coil spring 330 so that the mover 310 can move up and down by interacting with the elastic deformation of the coil spring 330 caused by the reciprocating motion of the transfer tube 200 when the user shakes the container body 100 or operates the nozzle assembly 110 using the pushbutton.

In another embodiment, multiple beads 321 can be placed in the direction the blades 320 are formed to increase the efficiency of mixing by adding loads on the blades 320.

These beads 321 allow each blade 320 to interact with the mover 310, or increase mixing efficiency by producing several swirls near the surface of the blade 320, depending on the motion of the blades 320.

At the same time, as illustrated above, the multiple blades 320 can be arranged in helical or radial shape with different heights along the outside surface of the movers 310, increasing mixing efficiency and helping maintain the quality of the contents 500.

In addition, as described above, these multiple blades 320 can be made as flat plates but also as frames with the edges illustrated as members of a steel wire or narrow, long rod. Multiple wires are then arranged width- and lengthwise, and multiple beads 321 can be coupled though so that the beads can freely rotate on each wire.

In other words, in the aforementioned embodiment, the user can lift up the container body 100 and shake it to allow the aforementioned ball 400 to maintain the quality of the contents 500, and make the quality maintenance unit 300 including the movers 310 and blades 320 mix the contents 500, contributing to quality maintenance.

In another embodiment as shown in FIG. 4, the efficiency of mixing the contents 500 can be increased using the elastic deformation of the mixing spring 350.

In other words, the user can apply to the quality maintenance unit 300 a structure in which a moving ring 340 is coupled to a mixing spring 350, and a mixing body 360 is coupled to the mixing spring 350.

Each moving ring 34 has a bigger inner diameter than the outer diameter of the transfer tube 200 and multiple moving rings can be coupled to the transfer tube 200 lengthwise, while mixing springs 350 are multiple members coupled to those moving rings 340 in helical direction allowing for elastic deformation.

The mixing body 360 is a heavy object coupled to each end of multiple mixing springs 350 and increases the efficiency of mixing the contents by increasing the motion caused by the elastic deformation of the mixing springs 350.

Also, these moving rings 340 can sink to the bottom of the internal space 101 due to the weight of the moving rings 340 if the container body 100 is not used for a long time. To prevent this, retaining ring ribs 370, 370 should be put in place.

The retaining ring ribs 370, 370 are arranged at certain intervals on the outside surface of the transfer tube 200, and a pair of them has a bigger outer diameter than the inner diameter of each moving ring 340, and moving rings are placed between a pair of the ribs 370, 370.

Here the retaining ring ribs 370, 370 can be integrated with the transfer tube 200, or can be made detachable.

If the retaining ring ribs 370, 370 are made detachable from the transfer tube 200, the spacing interval can be freely adjusted and moving rings 340 can be placed between a pair of the retaining ring ribs 370, 370, varying the amplitude of the shaking container body 100.

Therefore, if the spacing between the pair of retaining ring ribs 370, 370 becomes greater, the moving range of the moving rings 340 also becomes greater, increasing mixing efficiency.

Therefore, the technical idea of the present invention is to provide a container assembly which helps maintain the quality of the contents in the container body to ensure the contents can be ejected properly.

Also, this invention may be modified in various ways by a person who has common knowledge in this field within the extent of the basic idea of the invention.
